OpenCap vs Video Gait Analysis

OpenCap is a software system to measure 3D human movement from iOS device videos. It comprises an iOS app for video capture, a web app for data collection and visualization, and scalable cloud computing for biomechanical analysis from video.

Give your running store the tools it needs to deliver confident, expert-driven gait analysis. GaitAnalysis helps running specialty retailers and performance professionals record, review, and explain running mechanics with clarity—without outsourcing data to the cloud or relying on auto-generated assessments. Every video, every measurement, and every insight stays local and fully under your control. Designed to keep the workflow simple, reliable, and professional—no automated AI guesses, no cloud dependency—so the evaluation stays exactly where it belongs: in the hands of the experts who know their runners best. Key Features: • High-Quality Video Recording - Capture smooth 60fps video of customers running on a treadmill for detailed slow-motion analysis. Recordings run up to 3 minutes — plenty for a fitting, without filling your device — and the app warns you as the limit approaches. • Professional Analysis Tools - Draw lines, arrows, circles and angles directly on the video to highlight pronation, stride patterns, and form issues. Automatic angle measurement helps quantify over-pronation and supination. • Marks Anchored to Moments - Each mark appears at the point in the run where you drew it and holds for a few seconds, so several observations don't pile up on screen at once. Drag a marker along the timeline to change when it shows, or pin one as a plumb line that stays for the whole clip. • Notes That Travel With the Session - Describe what each individual mark shows, and keep your observations separate from your recommendation so the advice never gets buried in a paragraph. • Precision Playback Controls - Adjust playback speed from 0.125x to 2x, step frame-by-frame, and zoom up to 5x to examine every detail of running form • A Fitting That Finishes - Saving a session opens it with sharing right there, while the customer is still in front of you. Choose what they get — the video by email, a report, or a copy in Photos — and the app asks only what that choice needs. • Customer Management - Store customer profiles with contact information, shoe size, and weekly mileage for personalized recommendations and follow-up • Searchable Session Library - Quickly find past sessions by customer name, email, or phone number. Perfect for return customers looking to compare shoes or track progress. • Privacy-First Design - All customer data and videos are stored locally on your device. No cloud uploads, no accounts, no subscriptions, complete privacy. Pro Tools - one optional, one-time purchase. Never a subscription. • Send the Markup, Not Just the Video - Your marks drawn permanently into the video you share, so the customer sees exactly what you pointed at • Branded PDF Report - Your shop's name and logo on a report built from the moments you marked: each still captioned in your own words, knee and ankle angles printed as readable numbers, and your recommendation set apart at the end. Look it over before you send it, then email, print, or save it. • Save to Photos - Keep the annotated video in your camera roll Everything else stays free. Recording, playback, marking up, timing your marks, measuring angles, writing notes, saving sessions and emailing the video work exactly as they always have. Perfect For: - Running specialty stores - Athletic trainers - Physical therapists - Running coaches - Shoe fitting specialists Make every interaction count with GaitAnalysis — the professional tool trusted by retailers, trainers, and movement professionals. ---- Terms of Service: https://nigelware.com/legal/gait-analysis/terms-of-service Privacy Policy: https://nigelware.com/legal/gait-analysis/privacy-policy https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
